Abstract (en)
[origin: GB2605606A] A screening system includes a detection apparatus (100, fig.1), a rotatable platform 310 to receive the item, and a mechanical arrangement 320, 330. The detection apparatus has an emitter portion to generate a primary beam (130, fig.1) of ionising radiation, such as x-rays or gamma rays, and a detector portion to detect an absorption signal and at least one of a diffraction signal and a scattering signal. The mechanical arrangement is adapted to translate the detection apparatus along a translation axis 315 to scan the item with the primary beam. The detection portion may be formed of an ionising radiation absorption sensor 140, a collimator 150, and an energy resolving detector 160 for detecting the energy of scattered or diffracted photons in the sample (180, fig.1). The system may comprise a data analyser 350 which may form a first absorption image and a second diffraction or scattering image. A tomosynthesis reconstruction algorithm may be used. Image segmentation may be performed to identify regions of interest. The screening system may be used for identifying restricted or illicit substances that may be present in some luggage or in mail.
